The convergence of microwave technology and machine learning has fostered the development of smart radar systems. This paper introduces an energy-efficient radar system for object classification, employing a microcomputer mediated interaction between radar and deep learning model. Specifically, our approach focuses on Ground-Based Synthetic Aperture Radar (GBSAR) and utilizes a Raspberry Pi microcomputer to dynamically adjust the number of positions from which GBSAR sensor obtains measurements. The system operates in two phases: initially recording the scene from reduced number of positions, followed by capturing segments of the scene that contain objects classified below a preset certainty from additional positions. Experimental findings highlight consistent improvements in classification accuracy across all test scenarios. This methodology enhances both energy efficiency and classification outcomes, effectively balancing resource consumption and accuracy.
